The sensor and alarm system’s reaction time is in the range of less than one second.
The SOPS and the sensors are identically for each engine. Due to differences in
each engine design which result in different wall thicknesses different SOPS and
sensor lengths are required. The needed length will be determined by personell of
MSS AG or an authorized partner.
If the SOPS and the sensor are installed near or in a section with a high splash
oil concentration the usage of the Diffusor add-on is required (also refer to “2.2.
Installation Position” on page 2.2).
Important for users of Gas Engines
The GDMS-OMD14 consists of an appropriate component (electronic system) and
an intrinsically safe component (Sensor). These components build a mechanical
unit.
The GDMS-OMD14 is mounted to the engine wall, separating the crank case with
its Ex-category 2G requirements, from the non explosive engine room.
The cylindrical Aluminium housing containing the electronic system is an assembly
of circuit boards and electronic components.
Two plug connectors for connection of the non intrinsically safe electric circuits
(current supply and RS 485 interface) and the electronic system of a further Sensor
are mounted to the cylinder barrel of the cylindrical housing.
The cylindrically shaped high-grade steel housing of the sensor consists of an
optical system and a temperature sensor. The electronic components, except the
optical measuring section, are embedded in explosion proof pottant.
The housing of the sensor and the electronic system are connected to each other
by a threaded pipe. The multi-core connecting cable of the intrinsically safe electric
circuits of the sensor is led through the threaded pipe and connected to the circuit
board of the electronic system.
